Double damping flywheel crew of a tilting damper

The invention relates to a dual mass flywheel (1) for a motor vehicle comprising: - a primary flywheel (2), having an annular chamber (9) filled with a lubricating agent, and a secondary flywheel (3); - a torsional elastic bodies for transmitting torque and cushion the acyclic rotation between the primary wheels (2) and secondary (3), said torsion damper elastic bodies having first and one second stage damping; - an oscillating damper (49) comprising a support member (50) rotatable about the axis O and pendulum weights (51) movably mounted on the support member (50); wherein the support member (50) is constrained to rotate with intermediate support elements (45) acting between the elastic members of the second damping stage, by means of fasteners (46 ) passing in sealed manner the sealing means (63, 64) extending between the primary wheel (2) and the secondary wheel (3).
